It's my understanding that the result has the same problem as some of the new
lifters; they are too soft. At any rate, I had some original lifters reground
years ago by Babe Erson, and after only 10,000 miles or so, they had started to
spall and break up.
Since then, I have heard Kas Kastner's advice to run a new camshaft/lifters at
a fast idle for 20 minutes or so (which contradicts many other's advice about
driving the engine). He claims that will work harden the lifters and cam lobes.
Also, Greg Solow (The Engine Room) and Ken Gillanders (British Frame and
Engine) both have new lifters that work. (Likely others too, those are just
the ones I've heard about.) Greg does a 100% test on his new lifters, while
Ken has a solution from a different engine.
There is also the whole fuss about reduced ZDDP levels in modern motor oil
being a problem for "flat" lifter engines, but I'm not convinced that applies
to stock TR motors. Still, it wouldn't hurt to throw in a can of GM's EOS
additive during break-in (which contains ZDDP).
